Measuring focal length and refractive index of a lens using Moire technique
In this paper the calculating formula of the Talbot length under the condition of the light fields of converging spherical waves is given, and a new method of measuring the focal length and refractive index of a lens with Moire technique ig presented. It avoids the deficiencies of other methods proposed in the recent two years.
